out the PVT system, shift the transmission to
neutral and rev engine slightly to expel the
moisture and air-dry the belt and clutches. Allow
engine RPM to settle to idle speed, shift
transmission to lowest available range and test
for belt slippage. Operate ATV in lowest available
range for a short period of time until PVT system

ENGINE OIL LEVEL

To check the oil level:
1. Set machine on a level surface.
2. Start and run engine for 20-30 seconds. This will
return oil to its true level in the engine sump.
3. Stop engine, remove dipstick and wipe dry with a
clean cloth.
4. Reinstall dipstick, screwing into place.
5. The dipstick must be screwed completely in to
ensure accurate measurement.
6. Remove dipstick and check to see that the oil
level is in the normal range. The oil should be
between the top of the bottom crosshatched area
and the bottom of the top crosshatched area. Add
oil as indicated by the level on the dipstick. Do not
overfill.
Normal Oil Operating
Range is between crosshatch.

NOTE: Do not fill the over the normal oil operating
range. Filling over the normal operating range could
cause a mist of oil to enter the air box.
NOTE: Rising oil level between checks in cool
weather driving, can indicate moisture collecting in the
oil reservoir. If the oil level is over the full mark,
change the oil.
